My most recent beef is with the Science Channel’s ‘Prophets of Science Fiction’ episode on Philip K. Dick. In this episode it was asserted that the fiction of Dick anticipated ‘parallel words’ which may be implied by recent work in theoretical physics.
In nontechnical language, string theorist Brian Greene explains how our understanding of the universe has evolved from Einstein's notions of gravity and space-time to superstring theory, where minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe.
A complex form of mathematical symmetry linked to string theory has been glimpsed in the real world for the first time, in laboratory experiments on exotic crystals.
It's easy to understand how three or even four dimensions work, but how about ten? Or one and a half? Or none? Prepare your mind for boggling!
